Observation of an electric quadrupole transition in a negative ion: Experiment and Theory
C. W. Walter, S. E. Spielman, R. Ponce +4
The first direct experimental observation of an electric quadrupole (2) transition between bound states of an atomic negative ion has been made. The transition was obse…
Magic Wavelengths of the Yb Intercombination Transition
T. A. Zheng, Y. A. Yang, M. S. Safronova +4
We calculate and measure the magic wavelengths for the intercombination transition of the neutral ytterbium atom. The calculation is performed with th…
Competition between Factors Determining Bright versus Dark Atomic States within a Laser Mode
Bryan Hemingway, T. G. Akin, Steven Peil +1
We observe bimodal fluorescence patterns from atoms in a fast atomic beam when the laser excitation occurs in the presence of a magnetic field and the atoms sample only a portion o…
Detection of missing low-lying atomic states in actinium
Ke Zhang, Dominik Studer, Felix Weber +10
Two lowest-energy odd-parity atomic levels of actinium, 7s^27p 2P^o_1/2, 7s^27p 2P^o_3/2, were observed via two-step resonant laser-ionization spectroscopy and their respective ene…
Optical clocks based on the Cf and Cf ions
S. G. Porsev, U. I. Safronova, M. S. Safronova +4
Recent experimental progress in cooling, trapping, and quantum logic spectroscopy of highly-charged ions (HCIs) made HCIs accessible for high resolution spectroscopy and precision…
